Recent developments in praxis and theory of religious education point to the growing interest in inclusive forms of didactics. Interreligious learning invites children and young people to deal constructively with religious diversity in the classroom. In this paper, philosophical and theological arguments for inclusive religious education are presented and widened for a learning environment in which people with and without special needs learn in each other's presence. The experience of radical otherness, of difference and vulnerability of fellow learners, is the starting point to reframe religious didactics, religious pedagogy and theology. It is also the culmination point: radical inclusive religious education ends up with the experience of learning as "receiving the gift of friendship" (Hans Reinders). This framework is helpful to plan different sorts of learning arrangements and to conceive of different sorts of learning relationships, even outside the religious education classroom.
